    Michael S. Tsirkin discovered that QEMU incorrectly handled vmxnet3 devices. A local guest could possibly
    use this issue to cause a denial of service, or possibly execute arbitrary code on the host. This issue
    only applied to Ubuntu 13.10 and Ubuntu 14.04 LTS. (CVE-2013-4544)

    Michael S. Tsirkin discovered that QEMU incorrectly handled virtio-net MAC addresses. A local guest could
    possibly use this issue to cause a denial of service, or possibly execute arbitrary code on the host.
    (CVE-2014-0150)

    Benot Canet discovered that QEMU incorrectly handled SMART self-tests. A local guest could possibly use
    this issue to cause a denial of service, or possibly execute arbitrary code on the host. (CVE-2014-2894)
